Transposistion of formula

  1. Aug 17, 2008 #1
    Can anybody please transpose the following formula..

    f=1/2*pie * Sqrt L*C - Resonant Frequency Formula.

    I know value for L and F but require C.

    Anyone help or show me how - I have spent ages on this and my brain has gone soft :confused:

    Cheers

    It is just an algebraic manipulation. To isolate the C, square both sides to get rid of the square root sign. Then just use your regular algebraic manipulation to get the C isolated all by itself on the lefthand side (LHS) of the equation. Does that help? What answer do you get?


    EDIT -- I'm moving this to the Homework Help forums, where homework and coursework should be posted.

    Just for clarification, did you mean ?
    f = 1/[2*pi*Sqrt(L*C)]

    I also recommend the procedure that Berkeman suggested. If you show us what you have got so far, we can help steer you in the right direction.
